AXLE-BOX.

SPECIFICATION forming part of Letters Patent No. 663,189, dated December 4, 1900.

Application iiled April 7,1900. Serial No. 11,943. (No model.)

To (LZZ whom, it Wawy concern/ Be it known that I, BLACK SMITH E. TAK- KEN, a citizen of the United States, residing at Holland, in the county of Ottawa and State of Michigan, have invented certain new and useful Improvements in Axle-Boxes, of which the following is a speciiication.

My invention relates to an improvement in axle-boxes; and its object is to provide an improved construction of axle-box and wheelsecuring means whereby dust and dirt are entirely excluded from the axle-bearing.

The construction of the improvement will be fully described in connection with the accompanying drawing and its novel features defined in the appended claims.

The drawing represents a longitudinal section of an axle, axle-box, and securing means embodying the invention.

The reference-numeral l designates the axle-spindle, formed with a central longitudinal oil-passage 2, extending from the outer end of the spindle to about the center thereof and communicating at its inner end with a transverse oil-passage 3.

4 designates the axlebox fitting over the spindle and externally threade'd at its outer end to receive an internally-threaded cap 5, having a .central threaded opening 6, registering with the outer end of the oil-passage 2 and adapted tobe closed by a screw-plug 7.

The inner end 8 of the box 4 is circumferentially enlarged and externally threaded to be engaged by the internally-threaded flange 9 of an inner cap l0.

The inner surface of the end 8 of the axlebox is formed with an annular recess ll, within which ts a collar l2, formed integral with a sleeve 13, which extends through the cap lO and is secured to the spindle bya transverse pin or holt 14. The outer surface or shoulder l5 of the collar is overlapped by the cap 10.

16 designates a set-screw extending through an internally-threaded horizontal opening 17 in the cap l0 and adapted to impinge against the inner edge of the axle-box, as shown, to compensate for wear.

Oil is supplied to the passages 2 and 3 by removing the plug 7, and the oil finds its Way to the space between the spindle and axlebox, as will be apparent.

As the outer ends of the box and spindle are closed by the cap 5 and the inner end of the box by the collar l2 and cup 10, the latter overlapping the former, dust and dirt are excluded from the axle-box and the free revolution of the axle-box and Wheel is insured.

I claiml. The combination with an axle-spindle formed with a longitudinal oil-passage connecting with a transverse passage, of a box surrounding the spindle and externally threaded at its outer end; an internallythreaded cap formed with a central opening; a screw-plug for closing the opening in the cal); sleeve secured to the spindle and tting an annular recess formed in the inner end of the axle-box, and a cap for closing the inner end of the box.

2. The combination with an axle-spindle formed with a longitudinal oil-passage; of a box surrounding the spindle, said box being externally threaded at its outer end, and circumfereutially enlarged andv externally threaded at its inner end; an internallythreaded cap fitting over the outer end of the box, and having a central opening; a screwplug for closing said opening; a sleeve secured to ILhe spindle and having a collar fitting an annular recess at the inner end of the box; a cap fitting against the inner end of the box and overlapping said collar, and having an internally-threaded liange which engages the threads on the box; and a set-screw extending through the inner cap and adapted to im pinge against the inner end of the box.

In testimony whereof I affix my signature in presence of two witnesses.

BLACK SMITH TAKKEN.
